Electrochemical cyclization of esters of propane-1,1,3,3-tetracarboxylic acids to give esters of substituted cyclopropane-1,1,2,2-tetracarboxylic acids

Conclusions Esters of substituted propane-1,1,3,3-tetracarboxylic acids cyclize to give high yields of esters of substituted cyclopropane-1,1,2,2-tetracarboxylic acids upon electrochemical oxidation in methanol in the presence of sodium iodide as an electron transfer catalyst.Translated from Izvestiya Akademii Nauk SSSR, Seriya Khimicheskaya, No. 1, pp. 228–230, January, 1987.
